Application value of laparoscopic ultrasonography in laparoscopic common bile duct exploration / 重庆医学

ABSTRACT

Objective To explore the value of the laparoscopic ultrasonography (LUS) in laparoscopic common bile duct explora-tion(LCBDE) .Methods 47 cases with cholecystolithiasis combined with bile duct dilatation or abnormal liver function were tested by conventional ultrasound ,magnetic resonance cholangiopancreatgraphy (MRCP) CT and LUS after LCBDE .All results were com-pared with the surgical findings and the intraoperative biliary endoscopy results .Results The diagnosis coincidence rate of conven-tional ultrasonography ,CT ,MRCP and LUS in 47 cases were 85 .1% ,72 .3% ,95 .7% ,100 .0% respectively .6 cases completed the surgery under the guidance of LUS ,1 case was converted to open surgery .Conclusion LUS is an examination method to avoid bile duct injury effectively and reduce postoperative residual stone in LCBDE .
